In case of a replacement of a CPU or memory on the main board, or if you need to remove the full main board, you need to first remove the top unit from the bottom unit. First, release the metal pin on each side of the module. Both metal pins must remain out when removing the top tray. Push the metal lever to its top position and pull it towards you to release the top unit from the locking mechanism.
Now carefully release the top unit from the bottom unit. If you need to replace a CPB board, you need to move both CPUs with heat sync. All memory DIMM modules, micro SD card, and all 4 DFM modules from the faulty CPB board to the new CPP board. Please note that a new CPP board will always be delivered preinstalled in a metal chassis. Start with the preparation of the new CPP board by removing the plastic covers on the CPU socket. Check the physical socket for any physical damage or bent or damaged pins.
Now start moving the components. Start by removing the CPU of the old CPP board. Make sure to read the instructions on the top of the CPUs. Follow the torque and order requirements. Please make sure to remove the screws backwards from 4 to 1 as explained in the specific video. Place the removed CPU with heat sink on the new main board and fasten the screws in the right order now from one. To 4 Continue these steps now with the 2nd CPU. Position them on the new main board and fasten it. Place plastic covers on the CPU socket of the damaged board.
Now move all DMMs to the new CPP board. Please refer to the specific video in case you want to see the needed steps again. After you have moved all DMM modules to the new board, check again if they are correctly locked by pressing on each module again. As the next step, you need to move the micro SD card from the old to the new board. The new board will always be delivered without this card. In case your customer was using a PCI Express raid controller, you need to change the internal SAS cabling of the new CPP board. First, remove the SAS loop back cable. Now cut the plastic tie strap on the cable of the optional SAS cable.
Remove the connector cover of the optional SAS cable. Now connect the cable to the connector. Now we continue on the front side. Move the 4 DFM modules from the faulty PCB board to the new CPB board. Check the related video to repeat the related steps. Before inserting a CPP board into the chassis, check each PCIE express connector and also the UPI connector for any damage. Also, take care that you don't touch the metal frame with the connectors during insertion.
Before inserting the UPI connecting box into the chassis, check each port for any physical damage or bent pins. To put the top unit back on the bottom unit, make sure the metal lever is in the correct position. It needs to be pointing towards you with the locking lever open. Place the top unit carefully back on the bottom unit. Push the metal lever back and check that the locking mechanism is working properly as demonstrated in this video. Pushed the lever back down in its normal position.
